Prompted by a discussion in another thread, I have the following question: the Arab alchemists in the ninth and tenth centuries proposed that all metals are composed of two basic "principles": Sulfur and Mercury. The union of alchemical sulfur and mercury in the perfect proportions should result in the Philosopher's Stone. But what about the salt ? As far as I know, Paracelsus added salt to create a trinity of alchemical elements. Unfortunately, I do not know any more sources that support this assumption. Does anyone know more about this ?
